r77 I. INTRODUCTION This Report issues my findings regarding the Nitrate Loading and Soil Suitability Studies completed for the proposed Minor Subdivision for property owned by Mr. Robert C. Bowen. These Studies were completed to examine the underlying soil characteristics to determine the suitability of on-site decentralized wastewater management systems for residential use, commonly referred to as septic systems. These Studies provide the San Joaquin County Environmental Health Department(EHD)with their required information pertaining to the current status of the soil and underlying groundwater, regarding the nitrate loading potential from the current and future wastewater disposal systems on the subject Parcel. This report complies with San Joaquin County Development Title, Section 9-1105.2(d). Mr. Bowen, and his daughter Lisa Jennings, have provided the preliminary information to complete these Studies. Within the text of this Report, Bolded Section (§)numbers are referenced at the beginning of an applicable Paragraph(s), or Appendices that correspond with the EHD Requirements Checklist. Section Numbers referenced as SSS§, are sections applicable for the Soil Suitability Study Requirements Checklist. Section Numbers referenced as NLS§, are sections applicable for the Nitrate Loading Study Requirements Checklist. Other portions of text may also apply to other sections of the Checklists, but may not necessarily be referenced. NLS§2.3, SSS§ 3.1. The subject property is 800 ft south of the intersection of North Cherokee Road and Liberty Road in an unincorporated area of the County. Municipal sewer and water will not expand to this area for a number of decades. The Assessor's Parcel Number APN1�V a n pendia B.illustrates the future layout of the proposed Parcels to form he Minor Subdivision This project is a Zone Reclassification with a of Line Adjustment to create fourccls. e San Joaquin Community—$eveia n ment requires that a Nitrate Loading/Soil Suitability Study be submitted to EHD before submitting the Zone Reclassification Application. SSS§ 1.1, 1.2. The SJC District Viewer Map indicates the subject Parcel is currently 13.09 acres net. Each proposed Parcel acreage is found on Page 4, which describes perc testing for each Parcel. This acreage is also referenced on Page 9 for individual nitrate loading calculations for each individual Parcel. Proposed Parcels 1 and 3 currently contain a single family residential (SFR) structure. Present land use of the property can be observed by the attached Site Plans and aerial Google Maps. The testing protocol has found the indigenous soils under the subject property to contain a predominate lean clay/silty fine sand soil material possessing slow permeability with variability throughout the property. This region of the County is known for clayey,tight soils with slow permeability. Percolation test results reveal perc rates failing(except for proposed Parcel 4), or slightly exceeding the maximum allowable rate,thus the requirement for engineer recommended disposal systems on the two Parcels to be built upon.
